Pi-Day Catapult — Optimize Angle & Tension (Predict vs. Measure) | MS–HS NGSS
Description (NGSS included) Celebrate Pi-Day with a data-driven projectile challenge! Students tune angle and tension on a simple launcher, then predict vs. measure range and compute percent error. Teams graph Range vs. Angle (and optional Range vs. Pullback) and explain results with CER. 🧠📈 🔬 Investigate: hold one variable constant to fairly test the other. 🧮 Model: use a calibration shot or R ≈ (v²·sin(2θ))/g to predict. 📊 Analyze: compare predicted vs. measured; percent error
